Geophysical monitoring of the ground above active supervolcanoes shows that it rises and falls as magma moves beneath the surface of the Earth. Silica-rich magmas -- like those in the Yellowstone regi...
We present results of a series of large-scale experiments to measure the coefficient of restitution for 1-m-diameter rocky bodies in impacts with collision speeds up to 1.5 m s1. The experiments wer...
The heterogeneity of the continental crust has a first order control on the dynamics of plate tectonic processes and the compositions of the Earth in both time and space. Heterogeneity can be characte...
To most people "geothermal electricity" conjures up images of a steam-enshrouded facility in a place like Iceland where heat from the depths of the Earth comes to the surface. But some geologists – in...
Implications of surface weathering of rapakivi granite outcrops for natural stone evaluation were studied in the Wiborg rapakivi granite batholith in southeastern Finland. The study was performed as f...
中山大学地球科学系陈国能教授和洛尼.格拉佩斯教授合著的英文专著《Granite Genesis: In-Situ Melting and Crustal Evolution》于2007年由Springer首次出版。该书提出了与传统岩浆侵入论截然不同的花岗岩成因学说——“原地重熔-壳内对流说”,引起了国内外学术界的关注和产业部门的重视。为满足国内读者的需求,彭卓伦、张献河、胡文烨、张珂(校)等将该书...
The Dongrae thermal water area located at the southeast margin of the Korean Peninsula is one of the oldest hot springs in Korea and has been used in spas since the 9th Century. In this paper, a geoch...
valley slope. 4 Conclusions and discussion 4.1 Conclusions 1) In the weathering granite regolith section of riverbed, Al2O3 trends toward decreasing, Fe2O3 enriches at great ratio, th...
In this study, the effects of granite-grit offered free-choice on voluntary intakes of grit and subsequently on some morphologic traits of the digestive tract and performance of broilers were investig...
Abstract: The formation of kaolin-group minerals in the weathering profile of granite, under the humid, temperate climate as found in Korea, was studied by X-ray diffraction (XRD), scanning electron m...
The Skiddaw Granite and its contact metamorphic aureole in the English Lake District provide an excellent opportunity to test the capability of the N-isotope system to trace devolatilization and larg...
Accessory monazite crystals in granites are commonly unstable during amphibolite fa-cies regional metamorphism and typically become mantled by newly formed apatite-allan-ite-epidote coronas. This dist...

The temperature and chemistry of hydrothermal fluids control the breakdown and for- mation of beryl in rocks of appropriate bulk composition. In rocks of the Triberg granitic complex in the Schwarzw...
Clay fractions separated from the A2, B, and C horizons of a soil formed on granite gneiss showed X-ray powder diffraction (XRD) spacings characteristic of trioctahedral illite. The trioctahedral illi...
